Cytokine transcriptome profiling in acute experimental canine atopic dermatitis skin lesions after IL‐31 inhibition with lokivetmab

Veterinary Dermatology, Volume 34, Issue 4, Page 327-338, August 2023., 2023
Background – The caninised monoclonal antibody lokivetmab (LKV), directed at interleukin (IL)‐31, is very effective at controlling pruritus in most dogs with atopic dermatitis (AD). However, evidence exists that IL‐31 is not required for the induction of acute allergic skin inflammation, which might explain why this treatment is less efficacious in ...

Mussel parasite richness and risk of extinction

Conservation Biology, Volume 36, Issue 6, December 2022., 2022
Abstract Parasite conservation is important for the maintenance of ecosystem diversity and function. Conserving parasites relies first on understanding parasite biodiversity and second on estimating the extinction risk to that biodiversity. Although steps have been taken independently in both these areas, previous studies have overwhelmingly focused on

An international seroprevalence survey of the IgE sensitisation to the Dermatophagoides farinae house dust mite and two of its major allergens (Der f 2, Zen 1) in atopic dogs

Veterinary Dermatology, Volume 33, Issue 2, Page 117-e34, April 2022., 2022
Background – Dogs with atopic dermatitis are often immunoglobulin (Ig)E‐sensitised to Dermatophagoides farinae (Df) house dust mites, yet limited data exist on the sensitisation rates to the individual Df allergens, Der f 2 and Zen 1. Objectives – To determine the IgE sensitisation rates to Df, Der f 2 and Zen 1 in atopic dogs from geographically ...
